Question 4 of 25
Gnoma [55]

Answer:

Step-by-step explanation:

We are looking for P(58 < x < 64). We need to find the percentage to the left of the z-scores for each of these numbers. To find the z scores, use the formula:

z=\frac{x_i-\bar{x}}{\sigma}

z=\frac{58-62}{4} which gives us a z-score of -1. The percentage of numbers to the left of a z-score of -1 is .1586553

Now for the other z-score:

z=\frac{64-64}{4} which gives us a z-score of .5. The percentage of numbers to the left of a z-score of .5 is .69146246

The lower percentage subtracted from the higher gives the area in question:

.69146246 - .1586553 = .53280716, or as a percentage, 53.3%, choice A.

How do you graph a linear equation?<br><br>For example, -18x+9y=72
nikdorinn [45]
Basically with the example you have you need to have the x and y variables on different sides. 
Equation: 
-18x+9y=72    (now you want to add 18x on both sides)
<u>+18x          +18x
</u><u>9y=72+18x </u>   (next you divide 9 to both sides to get x and y alone) 
      9 
y=8+2x (now that you have the x and y alone this is the final equation) 

On the graph you want to put a dot on 8 since it's the y-intercept or the starting point of the equation. After that you want to add 2 every time you go by 1 on the x-axis. I have a picture of a graph...

<em>I hope this help you out :D</em>

When dealing with an equation containing two variables, we can put the graph of the equation on the coordinate plane because the
Luden [163]

Answer:

Step-by-step explanation:

A linear equation with two variables may appear in the form of Ax + By = C, and the resulting graph is always a straight line. The equation is more often in the form of y = mx+b, where m is the slope of the line of the corresponding figure and b is its Y-axis intercept, that is, the point where the line meets the Y-axis.

For example, 4x + 2y = 8 is a linear equation because it fits the desired structure. But for graphical and most other purposes, we often write this as y = - 2x + 4.

In this unit, on the basis of this linear equation, the equal sign is changed to the greater than a sign or less than sign, which is a new challenge in the operation of symbols.
